deep purple needle crystals (in pyridine) or purple crystals. Melting point 268 °c. Soluble in benzene, pyridine, nitrobenzene, aniline, slightly soluble in hot acetic acid, ethanol. In concentrated sulfuric acid solution is almost colorless, after adding boric acid blue red.
1, 4-hydroxyanthraquinone was obtained by condensation of hydroquinone and phthalic anhydride, which was refined with sodium hypochlorite and then ammoniated to obtain 1,4-= aminoguantrone leuco, and then oxidized by fuming sulfuric acid to obtain the finished product.
The intermediates of anthraquinone vat dye, disperse dye and acid dye are themselves disperse dye Violet.
